SIB on a roof rack

[Robert31]

Citroen Berlingo van with2.7 LOA sib, 30kg, any ideas of a DIY roof mounting method. \single handed for preference. Some expensive options available, but there are inventive geezers here. Not too cumbersome for preferance.

If your SIB is a flat bottom slat floor type - a flat surface will be best to spread the weight.
I use a bit of 3/4 inch ply with u bolts clamped to the roof bars to carry my little Seago on the roof whilst deflated in it's carry bag.
The roof bars normally have 4 cycle carriers mounted on them so I remove 2 carriers and clamp the padded board on - thus still allowing me to carry 2 bikes and sib on the roof.
My engines and other Sib gubbins go in the boot
The ply is covered with rubberised foam and I have painted it black since the photo was aken.
I used 3 x 800kg ratchet straps to secure the Sib down.
Have only used this method once - it was a 60 mile round trip and I hit 60mph no worries with thd load still intact upon my return:thumbup:
You could mount a bigger / wider board to your roof and strap your sib onto this.

I think it depends on your need. Are you looking for a slide down lift on, slide up arrangement as in the ones used for canoes? If so cheapest place will be a scrap yard where they have a ladder gantry from a fire engine.

When I had my sib i carried it upside down on the roofrack. I had a 2nd seat of bars that I clamped on running front to back for the tubes to sit on and at 3.83 had no issues, travelled better upside down, nose first.

A small trailer may be better, or perhaps build a specific thing for the sib to sit on connected to the roof rack and properly secured. Im not sure how secure it would be in the event of an accident.

I spotted a week or so ago I chap in a landrover defender towing a small pop up show stand with a 3m sib with a v hull sitting on top of his landrover roof, no roof rack and just a couple of straps over the sib, looked well dodgy.

I tried single handed roof mounting my avon r320 on my hyundai i20.
It fell off while I was trying to lift it on and damaged the car.
Lesson learnt.
Wouldn't want to try it on a van!
Saying that, can't you get the van roof racks that have both the spinning rollers instead of bars? and also have the vertical pieces on the ends to stop it falling off the sides? That would have sorted my problem.
